N=4 string is the same as the N=2 string.

We redo the quantization of the N=4 string, taking into account the reducibility of the constraints. The result is equivalent to the N=2 string, with critical dimension D=4 and signature (++−−). The N=4 formulation has several advantages: the σ-model field equations are implied classically, rather than by quantum/β-function calculations; self-duality/chirality is one of the super-Virasoro const...

DEVELOPMENT IN STRING THEORY

The string theory is a fast moving subject, both physics wise and in the respect of mathematics. In order to keep up with the discipline it is important to move with new ideas which are being stressed. Here I wish to give extracts from new papers of ideas which I have recently found interesting. There are six papers which are involved: I ."Strings formulated directly in 4 dimensions " A. N...

Drill string Vibration Modeling Including Coupling Effects

Abstract: The governing equations of motion for a drill string considering coupling between axial, lateral and torsional vibrations are obtained using a Lagrangian approach. The result leads to a set of non-linear equations with time varying coefficients. A fully coupled model for axial, lateral, and torsional vibrations of drill strings is presented. The bit/formation interactions are assumed ...

What is String Theory?

We describe, for a general audience, the current state of string theory. We explain that nature is almost certainly not described by string theory as we know it, but that string theory does show us that quantum mechanics and gravity can coexist, and points to the possible theory of quantum gravity which describes the world around us. Directions for research, both on the nature of this theory an...
